Electromagnetic inductive drive and method of making the same

Abstract

An improved disc drive. The disc drive having a generator assembly and method of making thereof includes at least one data storage medium; a rotor magnet attached to the edge of each data storage medium; and a stator magnet spaced apart from the rotor magnet. The disc drive data storage system further includes a pivot shaft; at least one actuator mounted to the pivot shaft; at least one read/write head mounted to the distal end of the actuator; a spindle motor; at least one spacer ring; and a spindle hub. The spindle hub retains the data storage medium and the spacer rings to the spindle motor in an assembled relationship; and a junction. Either the rotor magnet or the stator magnet, or both, may be a coil magnet. An electric current is produced within the windings of a coil magnet by electromagnetic induction. Current generated within the coil windings of the magnet is transferred through a junction to the battery. The data storage medium is one of a hard disc, a compact disc and an optical disc.
